FROMLIST: fs/super: function to prevent super re-use The function is to be called from filesystem-specific code to mark a superblock to be ignored by superblock test and thus never re-used. The function also unregisters bdi if the bdi is per-superblock to avoid collision if a new superblock is created to represent the filesystem. generic_shutdown_super() skips unregistering bdi for a retired superlock as it assumes retire function has already done it.
